INCANDESCENT VAPOR-BURNER.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed June 1 0, 1905. Serial N0. 264,719.

To all whom it may concern:

Be it known that we, ARTHUR BLANOHARD, electrical engineer, residing at199 Inderwick road, Hornsey, London, England, and HARRY W001), engineer,residing at Wyatt road, Highbury, London, England, both subjects of theKing of Great Britain, have invented certain new and useful Improvementsin Incandescent Vapor-Burners, of which the following is aspecification.

This invention relates to an inverted flame oil vapor incandescenceburner; and has for its object improvements in oil vapor burnersparticularly adapted for burning petroleum of high flash-point althoughothersuitable liquid fuel may be used as for example the lighter liquidhydro carbons or alcohol. The liquid fuel is supplied to the burnerunder a pressure preferably of from one to ten pounds per square inch.

The invention consists of an oil vapor burner in which are combined thethorough heating of the liquid hydro-carbons (which for the sake ofbrevity we will hereinafter refer to as the oil) before reaching the ctorifice, an even vaporization producing a continuous stream of vaporinsuring a steady flame which is downwardly directed, quick and simplemeans of lighting, with facility for clearing o clreaning the parts ofcarbon deposit, etc.

The burner is constructed in the following manner:A properlyproportioned injector or mixing tube (the outlet from which is arrangedto cause the flame issuing therefrom to I be directed downwards into theincandescence mantle) is provided below with a perforated head andsuitable means of attachment for an incandescence mantle after themanner of the inverted type of incandescent gas burner. At the top ofthe said tube is placed, centrally the jet orifice from whence the vaporescapes in a downward direction.

Air inlets are provided and arranged in the shape of one or more tubesradiating horizontally outwards from the upper end of the injector tubeand terminating on the outside of a vertically disposed tube surroundingthe upper portion ofthe injector tube and forming the flue for theescape of the products of combustion. Any suitable globe holder may beprovided as desired for example a ring (carrying the globe of anydesired character) depends from the said flue and may be attached by abayonet joint or other suitable means, which may serve both to detachand form a meansto raise or lower the globe. on the outside of the saidflue a coronet or other device is disposed around the air supplies as aprotection against drafts.

The vaporizing apparatus is constructed as follows :A tube which mayadvantageously be disposed horizontally (containing a removable fillingof wire gauze or the like) is provided with a suitable connection forthe oil supply and may advantageously also serve to support the burnerand passes into and across the aforesaid flue into communication with atube advantageously a vertically disposed tube adjacent to and ifdesired attached to the side of the injector tube, this vertical tubeextends downwardbelow its connection to the horizontal tube to a pointjust above the mantle, the lower end being closed with a stout cap towithstand the high temperature of the flame which comes in contact withit. V The upper end of the said vertical tube terminates at the toporupper part of the burner where a screw plug is provided for cleaningpurposes; and said vertical tube communicates. with the jet orifice by asmall duct, which latter is also provided with a plug for cleaningpurposes, etc.

Means are provided for cleaning the jet orifice in suchwise that samecan be operated from the exterior without permitting escape of the vaporsuch means consisting for example of a small pin actuated through astufling box.

To supply the initial heat for vaporization a receptacle for alcohol issuitably arranged as for example an annular cup for alcohol may bemounted on the exterior of said injector tube and a funnel or conductortube arranged to direct into said cup the quantum of alcohol necessaryto start the lamp.

Referring to the accompanying drawings:Figure 1 is a plan and Fig. 2 avertical section through the burner and its appurtenances. Fig. 3 showsa complete portable lamp with our burner and reservoir attached; andFig. 4 shows a bracket lamp.

A is a mantle attached in the usual or any suitable manner to theperforated burner head B.

C is the mixing or injector tube.

D and D are air inlet tubes extending to the outside of the tube E, thespace inclosed by tube E forming the flue for the escape of the productsof combustion.

F is a coronet surrounding the tube E for shielding the air-ways againstdraft.

G is a circular flange attached to the tube E to carry the globe whichlatter may be attached thereto by the screws G or by any other suitablemeans.

I is a screwed union for attaching the burner to its support or fittingand to the oil supply.

H is the horizontal part of the vaporizer containing a removable fillingof wire gauze J.

K is Vertical tube communicating with the vaporizer tube H.

L is a duct connecting the tube K with the jet orifice M.

N and N are screwed plugs for cleaning purposes.

O is a pin (for keeping the jet orifice clear) passing through thestuffing box 0 and operated by the milled head P.

Q is a cup for alcohol for supplying the initial heat required to startthe vaporizing of the oil.

R is the tube through which the cup Q is filled.

Z is pump to pump air into the oil reservoir Y until the required airpressure is produced (inside the reservoir) on the oil.

To operate the lamp a suitable quantity of alcohol is poured through thetube R into the cup Q and ignited; and when the alcohol is nearlyconsumed oil is supplied to the tube H either by opening a cock (notshown) situated in any convenient point in the supply H and pipe, or incertain cases (as in Figs. 3 and 4) by simply operating the pump Z.

The va orizing is accomplished in the tubes K and the vertical tube Ktends to separate any particles of oil or moist vapor which may emergefrom the tube Hwhich oil or vapor will descend by gravity into the lowerand hotter part of the tube K, the dry vapor therein produced thenascending and passing throug the duct L to the jet orifice M whence itescapes into the mixing tube and after drawing in and being mixed withthe requisite quantity of air such mixture is ignited at the burner headB. Alcohol may be employed as the liquid fuel in place of liquidhydro-carbons if desired.

What we claim is In an oil-burner, the combination, with an uprightmixing tube, of a burner carried at the lower end of said tube,air-supply tubes leading laterally to said mixing tube at the upper endthereof, an upright vaporizing tube located alongside said mixing tubeand closed at its lower end, said vaporizing tube and said mixing tubecommunicating with each
